Electric vehicle battery enclosures and methods of assembling electric vehicle battery enclosures involve a base portion to hold one or more batteries that provide motive power to an all-electric or hybrid electric vehicle. An electric vehicle battery enclosure includes a cover portion to mate with the base portion to enclose the one or more batteries, and a sealant to create a bond between the base portion and the cover portion around an entire perimeter of the enclosure and to seal the enclosure based on a uniform height of the sealant around the perimeter of the enclosure.

An apparatus for a vehicle body including a rocker insert is provided. The apparatus includes a vehicle body including a plurality of metallic structure members and a lower portion operable to provide support to a floor surface within a passenger compartment of a vehicle and a rocker insert mounted to an in-vehicle side portion of the lower portion. The rocker insert includes an elongated bar portion including a hollow center portion including internal reinforcing web features. The rocker insert is oriented with respect to the vehicle body such that a longitudinal axis of the elongated bar portion of the rocker insert is parallel to an in-vehicle forward direction of the vehicle body.

A system for protecting a battery enclosure of a vehicle, comprising of a structural blocker configured to be fixedly attached to a side portion of the battery enclosure. The side portion faces a lateral direction, extending along a vehicle axis that extends between a front and a rear of a vehicle. The battery enclosure includes at least one cross member oriented along a lateral direction, wherein the structural blocker is configured to be aligned with an end of the cross member and localized to a region of the side portion proximate to the end of the cross member. The structural blocker is configured to transfer a side load from a structural component of the vehicle to the cross member.

Side impact protection of battery enclosures

A battery enclosure, support beam for a battery enclosure and method of manufacturing the support beam. The battery enclosure includes a base and the support beam is securable within the base. The support beam includes a body, a nut channel secured to the body, and a mechanical fastener attached to the nut channel. The nut channel is formed into a u-shaped channel. The mechanical fastener is attached to the nut channel and the nut channel is secured to the body of the support beam.

A battery electric vehicle includes a pair of spaced apart and substantially parallel longitudinal members and a floor pan coupled to and above at least a portion of the longitudinal members. A battery pack bay is defined below the floor pan, longitudinally between predefined front and rear limits, and laterally between the longitudinal members. A battery pack may be upwardly disposed within the battery pack bay, the battery pack including a pair of laterally spaced apart sides whereat the first battery pack is removably attached to the respective longitudinal members. The battery pack may be dimensioned longitudinally to occupy less than the entire longitudinal space of the battery pack bay. A closeout structure may be removably attached to the respective longitudinal members and one longitudinal end of the first battery pack.

Reconfigurable battery electric vehicle

An electric vehicle includes a body structure, a forward sub-frame, and a battery pack. The body structure includes first and second side rails. The forward sub-frame includes first and second side supports each having and extending longitudinally between forward and rearward end portions. The first and second side supports are located forward of, and substantially parallel to, the first and second side rails. The battery pack includes a support structure disposed beneath, and engaged to, the body structure between the first and second side rails. The support structure has a plurality of longitudinal components spaced laterally apart from one-another, and disposed parallel to the opposite first and second side rails. The rearward end portions of the first and second side supports are proximate to respective first and second longitudinal components of the plurality of longitudinal components.

An assembly for a vehicle to provide load distribution between the body of the vehicle and a battery contained in the vehicle includes a pair of body rockers, the body rockers being spaced apart and being substantially parallel to each other, a plurality of body cross bars that extend between the pair of body rockers, the plurality of body cross bars being spaced apart, substantially parallel to each other, and substantially perpendicular to the body rockers, and a plurality of battery cross bars that extend between the pair of body rockers, the plurality of battery cross bars being spaced apart, substantially parallel to each other, and substantially perpendicular to the body rockers, portions of the battery being located between adjacent battery cross bars. The plurality of battery cross bars, the plurality of body cross bars and the body rockers are configured to delay initiation of rocker plastic deformation.

A vehicle body structure deflector system for small overlap frontal impact includes a first shock tower and a second shock tower. A cross member is positioned between each of the first shock tower and the second shock tower. A first deflector is connected to the first shock tower and a second deflector is connected to the second shock tower. If one of the first deflector or the second deflector is contacted by a barrier during forward travel of the vehicle a portion of an energy of impact with the barrier is transferred through one of the first shock tower or the second shock tower, through the cross member and into the other shock tower. The portion of the energy of impact with the barrier generates a vehicle lateral displacement to dissipate the portion of the energy of impact.

A rail assembly configured to limit a lateral deformation of an intermediate portion of the rail assembly to a predetermined lateral deformation when the rail assembly is subjected to an external force includes an inner portion, an outer portion, and a web portion. The inner portion has an inner wall. The outer portion has an outer wall and is attached to the inner portion. The inner portion and the outer portion together form a hollow rail. The web portion is configured with a deformation initiator, disposed inside of the hollow rail, and attached to the inner wall of the inner portion and the outer wall of the outer portion. The web portion is configured to limit the lateral deformation of the intermediate portion of the rail assembly to the predetermined lateral deformation when the rail assembly is subjected to the external force.

A sound-damped vehicle panel assembly, such as a dash panel, is attached to a structural member with one or more weld joints. The vehicle panel assembly may include a main panel member, a sound-damping patch, and a sound-damping adhesive layer arranged therebetween, where the patch covers at least a portion of an acoustically active region of the main panel member. The weld joints that attach the vehicle panel assembly to the structural member are preferably located at weld openings formed in the sound-damping patch and/or the sound-damping adhesive layer so that the weld joint can be formed without melting and vaporizing the adhesive during the welding operation, as such an operation would likely require additional ventilation equipment and could impact the quality of the weld joint.

An impact receiving structure in a motor vehicle includes a vehicle frame having left and right frame rails extending longitudinally and cross frame rails extending transversely between the left and right frame rails. A vehicle body is mounted on the vehicle frame and has a transverse bulkhead and left and right A-pillars connected to the bulkhead. Left and right upper rails extend longitudinally above the front wheels and outboard of the left and right frame rails and are connected respectively to the left and right frame rails by left and right braces. Left and right deflector devices are mounted on the left and right frame rails forwardly of the front wheels and extend outwardly from the left and right frame rails to receive an impact force and transmit the impact force into the frame that would otherwise transmit through the left and right upper rail structures.
